Its possible
Gallon of water weighs 8lb.
I go up about 6lb throughout the day normally.

Yeah i thought he meant like actual muscle tissue by saying lbm. I had never considered water weight as part of lbm. I used to lose up to 12 pounds in a 2 hour wrestling practice so i know how much water you can lose. I used to train with some pro fighters that would cut over 20 pounds water weight over a couple days.

Yeah, 75-80% of muscle is water but all LBM actually means is Lean Body Mass, so anything other than fat that makes up the bodies mass. Like hair, bones, organs and the like.

Right i knew thats what it meant but what that meant to me was like muscle tissue and stuff like that i never reLly thought about water weight being part of that lol

Yeah I got you, but without the water it is so small not to think of it as muscle as it provides the volume to the muscle fibers. No I definitely did not lose 8lbs of actual tissue. Like you said, not even sure that is possible.
